Did you try the suggestion about putting the Flow Key in the top slot and turning a few times to double check all the cells are correctly aligned?
I have passed on your details to my team leader who will be emailing you personally to follow-up on this issue and see if we can find a solution.
Please check your inbox for any emails from Flow in the next couple of days.
